"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"Victor was very thorough, suggesting additional services that I needed but hadn't thought of...namely insulating the water lines in the attic. He not only added the blown-in insulation, but also sealed cracks and replaced or added vertical insulation on skylights and knee walls. All was done at a reasonable price, 25% less than the other bidder."

"When the initial man came to inform us of options, I knew right away that this is the company I wanted to hire! Very knowledgable from many years of experience. Answered all of our questions . Very professional & EXCELLENT Customer service. One thing we learned is not all Insulation contractors are honest. We learned that our past company (I can't remember their name) did not spray any insulation above our kitchen and the rest of the area was sparse & did not meet standard regulations. 805 Insulation has high standards & price was lower than we expected. We no longer have a draft coming from there! They also insulated the entrance and put in deflectors to direct any outside wind up over the insulation. They are the COMPLETE Package everyone needs to hire!!!!!! Donna D. in Los Osos, CA"

"Adam and his team of workers gave me a great deal on replacing the insulation in the attic. We had a leak in one of the fire alarm sprinklers that caused the insulation to be bad and smelly.
We spoke to Adam about the problem and he sent his employee (Luis) to come over and check the problem in order to provide us with a quote.
The quote that Adam was able to give us was very good and we approved the work. He than sent 2 workers to do the job and it was done in 2 days after they had to clean everything in the attic and to try it before they placed the new insulation.

"I would recommend Menaci Drywall Design to anyone looking for home repair work. They were quick to reply and answer questions, get info on what work needed to be done and scheduled an appointment to come do work. From first contact to completion was done in 3 days due to it being over Thanksgiving, had it been a regular week I believe it would have been done even sooner. The friendly and professional service is much appreciated!"

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
